Violence, erm I mean action

Hey, I'm kinda bored and looking for a good action manga (preferably senien). Something like Akumetsu or Gantz, Comedy is a huge up, and maybe romance, but not really as important, the important thing is lots of *** kicking. Oh, and nothing to depressing.

These all have some action, but I think Battle Angel Alita is the one that fits the most in regards of what you're looking for out of those three. And when you're done with BAA, you can start the sequel.
